Over the last 150 days we have learned much about the power of the habitual in post-millennial, post-apartheid South Africa. We have heard it in the grumbling, cavilling, quarrelling and grousing about the logic (or lack of) of government decrees. We have also seen it in the defiance of logic among the many bourgeois folks who mistook their entitlement for rights, whether to go running, do yoga on the beach, surf, get takeaway coffees, or to purchase items subjected to restricted trade… We saw it in the contradictory messages relayed by official government channels, in the conflict between some experts advising government, between government officials and such experts, and in the ways in which opposition parties contradicted themselves as they opposed government proclamations.
And you should know why the German regulations are a bad example of your case: the German political laws (5% minimum vote before election, etc) are there to exclude the possibility of another Nazi party emerging. The laws in Germany aren’t there for any good constitutional reason, they are there because of a political reflex against certain forms of extremism. No, that doesn’t mean they are a bad thing, but it doesn’t have anything to do with the constitutional validity of enforcing democracy in political parties by legal means.
I have three quick reactions to this argument. First, in a democracy the dominant political party will inevitably legislate in a way that will advantage them, but when there is a strong civil society and real contestation for power a dominant party will think twice before adopting legislation that would obviously rig the system.
Second, even where the rules favour the dominant party it is always better to have regulation that not having regulation at all because without any regulation the dominant party who can distribute patronage and has wide state powers, can easily go wayward. In any case a party like the ANC who experienced severe upheaval in the preparation of its election lists before the last local government election, may come to see the benefits of legislation that regulate the selection of candidates.
Lastly, Germany is not the only country who has adopted party laws. Other countries like Mexico has also done so and did so in reaction to a long history of corruption in the politics of that country. In a country with pure proportional representation a party law can help to stop the internal party corruption in the compilation of party election lists.
